The Short Answer
A full roof tear-off and replacement requires a permit from the City of The Colony Building Department. An overlay (reroofing over existing shingles) under 25% of roof area may be exempt, but The Colony's 2024 adoption of the 2021 IBC with local amendments means your contractor must confirm scope with the city before starting.
The Colony Building Department has adopted the 2021 International Building Code with Texas amendments, making roof tear-off projects subject to IRC R907 compliance inspection. This is notably stricter than neighboring cities like Frisco, which adopted 2015 IBC with grandfather rules for older homes. The Colony's online permit portal (accessible through the city website) requires a reroofing form and roof plan at submission; many contractors miss this and file in person first, delaying approval by 5-7 days. The city enforces a hard limit: any roof with three or more layers must be torn off to the deck (IRC R907.4), and inspectors photograph existing conditions before you start. If you're changing materials — say, from asphalt shingles to metal or tile — The Colony requires a structural evaluation (for tile/slate especially), which adds $500–$1,500 and 2-3 weeks to the timeline. Hurricane-zone secondary water-barrier requirements (FBC 7th edition, adopted locally) mean ice-and-water shield specifications must be detailed on your permit application, not left to contractor choice. Owner-builders can pull the permit themselves for owner-occupied homes, but the city's permit counter strongly recommends using a licensed roofer because plan-check rejections on underlayment and fastening specs are common among DIY filers.

What happens if you skip the permit (and you needed one)

The Colony roof replacement permits — the key details

The City of The Colony Building Department requires a permit for any roof tear-off, reroofing of over 25% of roof area, or material change (IRC R907.1 and R905). A like-for-like patch repair under 25% is typically exempt, but The Colony interprets this strictly: the city's own permit form asks the applicant to specify 'new roof area as percentage of total' and calculates by square footage, not visual estimate. If your inspection report or contractor notes say 'roof is at end of life' or 'widespread granule loss', the permit counter will classify it as over 25% and require a permit. The key trigger is whether you are tearing off the existing layer (tear-off = permit required) or laying new shingles over the old ones (overlay = potential exemption if under 25%). However, IRC R907.4 creates an absolute exception: any roof with three existing layers must be torn to the deck. The Colony inspectors photograph the roof in situ before permit issuance to enforce this rule. If a third layer is found during work, you must stop and file a new tear-off permit, costing an additional $150–$250 in fees and 7-10 days of delay.

Underlayment and fastening specifications are the #1 reason for plan-check rejection in The Colony. The permit application requires you to specify the weight and type of underlayment (synthetic vs. felt), ice-and-water shield coverage (typically required 36 inches from eaves in the Houston area due to ice dam risk, even though freezing is rare — this is per FBC and local amendments), and nail spacing (typically 4 inches on perimeter, 6 inches field, per IRC Table R905.2.1(1) for asphalt shingles). Many roofers assume 'standard practice' is acceptable, but The Colony's plan-check engineer will reject and ask for written documentation. Submit the roofing manufacturer's installation guide with your permit application to speed approval. If you are changing roof material — for example, from asphalt shingles to concrete tile or standing-seam metal — a structural evaluation is required (the weight difference is material: concrete tile runs 750+ lbs per square vs. asphalt at 225-250 lbs per square). The city will request a structural engineer's letter confirming rafters, trusses, and connections are adequate. This adds $500–$1,500 to your project cost and typically requires 2-3 weeks for the engineer to visit and issue the letter. Metal roofing is lighter and usually clears without engineering, but this still must be confirmed in writing at permit time.

The Colony is located in mixed climate and wind-zone territory (Denton County sits at the boundary between 2A and 3A, with some areas in 3B). However, the city's FBC adoption includes secondary water-barrier requirements that assume high wind and intermittent hail exposure. This means your permit must specify ice-and-water shield (or equivalent self-adhering synthetic underlayment) coverage beyond the absolute minimum — many North Texas cities omit ice-and-water shield entirely, but The Colony's plan-review memo specifically calls out ASTM D1970 or higher on 36 inches of the roof (eaves) and 36 inches up the rake (gable edges). Failure to specify this detail in the permit application leads to rejections. Additionally, if your home sits in a flood zone (check FEMA maps; parts of The Colony along the Lewisville and Elm Fork areas are in 100-year floodplain), the reroofing permit ties to floodplain-elevation certificates, and your roofer may need to provide site photos. These add-ons are rare but delay unprepared contractors by 2-3 weeks.

The online permit portal for The Colony is managed through the city's main website and requires you to upload a reroofing form (available as a PDF download), site plan showing roof dimensions and location, and itemized roofing material list (shingle grade, fastener type, underlayment). Unlike some Texas cities that accept hand-drawn sketches, The Colony requires a to-scale site plan or at minimum a labeled plat with dimensions in feet. The city's standard processing time is 2-3 business days for a like-for-like reroofing with complete submissions; partial submissions are sent back with a rejection letter citing missing documents (reroofing form page 2, manufacturer install guide, engineer letter for material change, etc.). Once approved, the permit is active for 6 months, and inspections are required at two points: (1) deck inspection before underlayment is laid (to confirm no rot, no third layer discovered), and (2) final inspection after shingles are installed. Many roofers schedule both inspections in one day-trip to keep the permit active. The colony's inspector availability is typically 2-3 week wait during March-September (spring-summer peak season) and 3-5 day turnaround October-February.

Owner-builder permits are allowed in The Colony for owner-occupied homes (the contractor is the owner). You will need to sign an affidavit stating that you own and occupy the property and that the work will be performed by you or your family members without contractor license. Even as an owner-builder, you must pull the permit before starting and schedule inspections. The city does not waive code compliance for owner-builders — IRC R907 and FBC secondary water-barrier requirements apply equally. Many homeowners try to have their roofer 'just start' while they apply for a permit, assuming retroactive approval is possible; The Colony's policy is that work discovered before permit issuance must stop, and the applicant must file a violation notice. After that, you can file for a permit, but the city may require the unpermitted work to be torn out and redone under inspection (costing $2,000–$5,000 more), or you can request a variance review, which costs $300–$500 and requires a hearing. It is far cheaper to pull the permit first.

Three The Colony roof replacement scenarios

Scenario A
Full tear-off and asphalt-shingle replacement, 2,400 sq ft home, no material change, single existing layer — Lakewood neighborhood, The Colony
You have a 25-year-old roof with one layer of 3-tab shingles and no visible damage — but a roofer's inspection shows granule loss and curling, and you want to replace with architectural shingles for durability. This is a full tear-off-and-replace, so a permit is required. The city's reroofing form asks: new roof area (100% of 2,400 sq ft = 2,400 sq ft), material change (no, same asphalt shingle class), existing layers (1). The plan-check engineer will not require a structural evaluation because asphalt shingles are like-for-like weight. However, the permit application must specify underlayment (you'll choose synthetic vs. felt — synthetic runs $0.50–$0.75/sq ft more but is easier for roofers and approved by The Colony's standard), ice-and-water shield coverage (36 inches from eaves, per FBC; your roofer submits the manufacturer's spec sheet showing ASTM D1970 compliance), and fastening pattern (4-inch perimeter, 6-inch field, per IRC Table R905.2.1(1)). You submit the permit online with a reroofing form, site plan showing roof area and dimensions, and the roofing material datasheet. Plan-check approval is typically 2-3 business days if complete. Permit fee is $180 (based on $0.08/sq ft of roof area for The Colony). Once approved, your roofer schedules a pre-tear-off deck inspection (city inspector looks for rot, verifies no third layer, and takes photos), then proceeds. Shingles are installed over 3-5 days, and the final inspection is scheduled. The inspector verifies fastener count/spacing on sample section, checks underlayment laps, confirms ice-and-water shield coverage, and signs off. Total timeline: 5-7 days from permit application to final approval (including inspection wait times during peak season; off-season is 3-4 days). Total cost: $180 permit fee + $9,000–$12,000 roofer labor and materials = $9,180–$12,180.
Permit required (tear-off) | No structural engineering | Synthetic underlayment + ice-water shield | Final inspection required | Permit fee $180 | Total project cost $9,000–$12,500
Scenario B
Overlay reroofing, 2,200 sq ft home, existing two-layer roof, like-for-like 3-tab shingles — North end, near Lewisville spillway floodplain
Your 20-year-old roof has two layers of worn 3-tab shingles, no structural damage to deck, and you want to roof over the existing shingles with new 3-tab to save money (no tear-off). This is a gray area in The Colony: an overlay on a two-layer roof is technically allowed under IRC R907.3 (overlay is permitted if total layers will not exceed two), but The Colony's online FAQ clarifies that the city 'requires confirmation at plan-check' because the existing layers must be inspected for hidden damage and the permit form asks the applicant to declare the number of existing layers. If you check 'two layers' on the form and the inspector photographs the roof and agrees, you can proceed with an overlay permit. However, there is a complication: your home sits within 500 feet of the Elm Fork floodplain (Lewisville spillway zone). The city's floodplain-management office requires that any roof work on a flood-zone structure include a floodplain-elevation certificate if the roof height changes or if structural modifications occur. A reroofing (overlay) does not change height, so the certificate is typically waived — but the permit-counter staff will ask. To avoid rejection, you should call the city's zoning division before filing and ask: 'Does my address trigger floodplain overlay requirements for a roof reroofing?' Many homeowners do not, and the permit is delayed 7-10 days while the city coordinates with floodplain management. Assuming no floodplain issue, an overlay permit is $120–$150 (flat rate or reduced rate for overlay vs. tear-off). Plan-check is 2-3 business days. The inspector will photograph the existing roof condition before you start, then perform a final inspection after shingles are installed. If the inspector discovers a third layer during the pre-work inspection, the permit is immediately downgraded to a tear-off requirement, and you must pay an additional $60–$100 permit fee and halt work for a new tear-off plan-check (5-7 days). This is the biggest risk with overlays: hidden layers discovered in the field. Total timeline: 4-6 days from permit application to final inspection (plus potential delay if floodplain flag is hit). Total cost: $120–$150 permit fee + $5,500–$7,500 roofer labor and materials for overlay = $5,620–$7,650.
Permit required for overlay (if 2 existing layers) | Floodplain check may delay by 7-10 days | Pre-work roof inspection mandatory | Hidden 3rd layer = mandatory tear-off upgrade | Permit fee $120–$150 | Total project cost $5,500–$7,500
Scenario C
Material change from asphalt shingles to concrete tile, 2,600 sq ft home, full tear-off — West side, Lakewood Village borders, slopes and exposed rafter tails
Your 18-year-old asphalt-shingle roof is failing, and you want to upgrade to concrete tile for durability and curb appeal. Concrete tile weighs 750-850 lbs per square vs. asphalt at 225-250 lbs per square — a 3x weight increase. This is a material change requiring structural engineering, which is The Colony's most stringent requirement. The permit application requires a structural engineer's letter stating that the home's trusses, rafters, connections, and load paths are adequate for tile load and for the tile fastening pattern (tile attachment requires more fasteners and heavier fasteners than shingles, per IRC R905.10). You will need to hire a local structural engineer ($500–$1,500 for a site visit and letter) and submit the letter with the permit application. Plan-check will not move forward without it. Once the engineer's letter is in hand, the reroofing form and permit submission includes: material change (shingles to tile), percent of roof affected (100%), existing layer count (1), structural approval (yes, engineer letter attached), and tile installation details (fastening per IRC R905.10, underlayment specification — tile requires a heavier synthetic or felt, typically 50-lb felt, which is more expensive than standard 15-lb felt). The city's plan-check engineer will review the structural letter and cross-check the roofing details. Approval typically takes 5-7 business days due to the engineering review. Plan-check rejection is possible if the engineer's letter does not specifically address tile load (some engineers write generic 'adequate for roofing' letters, which the city will bounce back and ask for tile-specific language). Once approved, the permit is issued at a higher fee: $250–$350 (tile reroofing is charged at a higher rate, often $0.15–$0.20/sq ft vs. $0.08/sq ft for shingle). Your roofer schedules the pre-tear-off deck inspection (city inspector verifies no damage, no third layer, and photographs). Tear-off is performed over 2-3 days, deck is inspected for rot (repairs if needed, which adds cost and timeline). Tile installation is slower than shingles — typically 7-10 days for a 2,600 sq ft roof. Final inspection includes verification of fastener type/count, underlayment laps, flashing compatibility with tile (a common issue: roofers forget to order tile-compatible flashing, and the inspector halts the final until it's corrected). Total timeline: 10-14 days from permit application to final approval (including engineer appointment, plan-check, and inspection waits during peak season). Total cost: $500–$1,500 structural engineer + $250–$350 permit fee + $15,000–$20,000 roofer labor and materials (tile is expensive) = $15,750–$21,850.
Permit required + structural engineering | Concrete tile requires engineer letter | Higher permit fee ($250–$350) | Heavier underlayment + specialized flashing | Longer timeline (10-14 days) | Total project cost $15,000–$21,000

The Colony's FBC adoption and hurricane-zone secondary water-barrier requirements

The Colony has adopted the 2021 International Building Code with Texas amendments, including Florida Building Code (FBC) Section 7 provisions for wind and moisture resistance. Although The Colony is not in a coastal hurricane zone (it sits in Denton County, about 30 miles north of the Dallas metroplex), the city's leadership chose to adopt FBC standards as a best practice for durability, especially after hail storms in 2020 and 2021. This means your roof reroofing permit must specify secondary water-barrier protection — typically ice-and-water shield or self-adhering synthetic underlayment — extending 36 inches from the eaves and 36 inches up the rake (gable edges). This is more stringent than neighboring cities like Frisco or Lewisville, which do not mandate ice-and-water shield on every reroofing. The cost difference is modest ($0.50–$0.75 per sq ft, or roughly $1,200–$1,800 on a 2,400 sq ft roof), but it is often not budgeted by homeowners shopping on price alone. When you call roofers for quotes, explicitly ask: 'Does your bid include ice-and-water shield coverage per The Colony FBC requirements?' Many contractors from neighboring cities underestimate the scope and underbid, only to discover at permit time that they must upgrade the materials list.

The FBC secondary water-barrier requirement exists because ice dams are a known risk in North Texas, even though freezing temperatures are rare. An ice dam occurs when snow or sleet accumulates on the roof, melts due to heat from the attic, then refreezes at the eaves (where it is colder) and traps water underneath. The water then seeps backward under the shingles and into the attic, causing rot, mold, and ceiling damage. The city's memo on this requirement notes that homeowners often wait until this damage occurs, then file insurance claims; the insurance company denies the claim if the policy excludes 'water damage from ice dam' (common exclusion). Specifying ice-and-water shield at permit time is The Colony's way of shifting responsibility to the roofer and the code, not the insurance company. If your home has a history of ice dams (water stains in the attic, ceiling damage, icicles hanging from the soffits), you should mention this to the permit counter and ask for extra ice-and-water shield coverage — the city's plan-check engineer will approve extending it further than 36 inches, and your roofer will not object because it is easier to lay than to argue about.

The secondary water-barrier requirement also applies to the rake edge (gable side). Many roofers focus on eaves coverage and forget the rake, leading to final-inspection corrections. At your final inspection, the city inspector will walk around the entire perimeter and visually confirm ice-and-water shield is present at both horizontal and vertical edges. If it is missing from the rake, the inspector will mark it as a correction, and your roofer must go back up and add it before a final sign-off. This typically costs an extra $200–$400 in rework and delays final approval by 3-5 days. To avoid this, confirm with your roofer in writing (email is best) that the contract includes ice-and-water shield per The Colony FBC spec, covering eaves and rake as specified in the permit plan.

The Colony permit processing: online portal, plan-check rejections, and inspection scheduling

The City of The Colony Building Department has migrated permit applications to an online portal accessible through the city website. To file a reroofing permit, you (or your roofer) must create an account, fill out the reroofing form (a multi-page PDF downloadable from the portal), and upload supporting documents: site plan, roofing material list, manufacturer installation guide, and engineer letter (if material change). The portal allows real-time tracking of plan-check status: submitted, under review, rejected, approved. Most complete submissions are approved in 2-3 business days; rejections are typically issued via email with a list of missing or incorrect items. Common rejection reasons include: (1) reroofing form page 2 incomplete (existing layer count, roof area percentage, material description unclear), (2) no manufacturer installation guide attached, (3) ice-and-water shield coverage not specified in detail (e.g., 'per manufacturer' is not specific enough — the permit engineer wants '36 inches from eaves, 36 inches up rake, ASTM D1970 or equivalent'), (4) structural engineer letter missing for material change or not addressing tile load, (5) site plan missing dimensions or roof slope notation. Resubmission turnaround is another 2-3 business days. This means a rejection can add 5-7 days to the timeline, which is significant during spring-summer peak season (March-September) when the city's backlog is heavy.

To minimize rejection risk, The Colony's building department recommends submitting applications on Monday or Tuesday morning (not late Friday), because the plan-check engineer has all week to review and you can resubmit corrections quickly. Additionally, calling the permit counter before filing (phone number available on the city website) to confirm submission completeness is wise. Many roofers skip this step, file incomplete applications, and then blame the city for delays. A 5-minute call to the counter can confirm: 'I have a reroofing project at [address], two-layer existing roof, asphalt to asphalt no material change. Do I need a structural engineer letter? Do I need a site plan, or is the address and roof dimensions enough?' The counter will give you a checklist, and you can file once. This simple step reduces rejection risk from 40% (blind submission) to <10% (guided submission).

Once your permit is approved, the city's online portal will issue a permit number and a link to schedule inspections. You (or your roofer) must schedule the pre-tear-off deck inspection and the final inspection through the portal or by calling the inspection scheduling line. Wait times vary by season: October-February, inspections are available within 3-5 business days. March-September (peak season), wait times are 10-14 days. Many roofers try to schedule both inspections in one day (morning pre-tear, then work all day, then afternoon final), but this only works if the deck is deemed acceptable at the pre-inspection — if the inspector finds rot or a hidden third layer, the final is cancelled and rescheduled. To keep momentum, schedule the pre-inspection as early as possible and plan to start tear-off work the same afternoon or next morning, so the final can be scheduled while work is underway.

Common questions

Do I need a permit to repair a roof leak or replace a few shingles?

No. Repairs under 25% of roof area are exempt from permitting in The Colony. This includes patching leaks, replacing damaged shingles, resealing flashing, and cleaning gutters. However, if the repair reveals a larger issue (e.g., rotten decking, mold), you must stop and notify the city — you may then be required to pull a full reroofing permit. Repairs on a roof with three layers must stop immediately and converted to a tear-off permit, per IRC R907.4.

My roofer says the roof can be overlaid without a permit. Is that true?

Not in The Colony. Any overlay on a roof with two or more existing layers requires a permit to confirm the layer count. The city enforces IRC R907.4: if a third layer is discovered, work must stop and a tear-off permit must be filed. Always get a permit for an overlay before work starts. The permit fee ($120–$150) is cheap insurance against a $2,000–$5,000 stop-work fine and forced removal.

What is ice-and-water shield, and why does The Colony require it?

Ice-and-water shield is a self-adhering synthetic underlayment (ASTM D1970) that is installed under shingles at the eaves and rake edges. It stops water from seeping backward under shingles if an ice dam or wind-driven rain occurs. The Colony adopted this requirement via FBC 7th edition because ice dams are a known cause of attic rot and mold in North Texas, especially in homes with poor attic ventilation. The shield costs $0.50–$0.75 per sq ft (roughly $1,200–$1,800 total on a 2,400 sq ft home) and is non-negotiable on any permitted reroofing.

If I change from asphalt shingles to metal roofing, do I need a structural engineer?

Metal roofing is typically lighter than asphalt (40-50 lbs per square vs. 225-250 lbs per square for asphalt), so a structural engineer is usually not required. However, The Colony's permit counter recommends submitting a letter from the metal roofing manufacturer confirming the weight and fastening requirements to speed plan-check approval. If you are switching to concrete tile or slate, an engineer letter is mandatory because tile weight can exceed the home's roof load capacity.

How long does the permit stay active?

Once issued, a reroofing permit is active for six months in The Colony. If work is not completed within six months, the permit expires and must be renewed (additional fee applies). During peak season (spring-summer), roofers work faster to avoid permit expiration. If your roofer takes longer than expected, you can request a six-month extension (usually approved once for no additional fee).

Can I pull a permit myself, or does my roofer have to do it?

Either you or your roofer can pull the permit. Owner-builders (owner-occupied homes) can pull it themselves without a contractor license. However, The Colony's staff recommend using the roofer to pull the permit because roofers are familiar with the plan-check requirements and can answer the engineer's technical questions (underlayment specs, fastener patterns, etc.). If you pull it yourself, be prepared to respond to rejections within a few days or the plan-check process stalls.

What happens if I start a roof replacement without a permit?

If discovered (via neighbor complaint, aerial inspection, or insurance claim), The Colony will issue a stop-work order, fine you $500–$1,500, and require the unpermitted work to be removed and redone under permit. Additionally, insurance companies often deny claims on unpermitted roof work, and title companies flag unpermitted reroofing during home sales, requiring a variance hearing or retroactive permit before closing. It is far cheaper to pull the permit upfront.

My home is in a flood zone. Does that affect the reroofing permit?

Yes, but only if the permit requires structural changes that alter the elevation of the roof. A reroofing (overlay or tear-off and replace) typically does not change height, so a floodplain-elevation certificate is waived. However, call the city's zoning division (469-624-3600) and confirm your address before filing to avoid a 7-10 day delay if the floodplain office is consulted during plan-check.

What is the typical cost of a reroofing permit in The Colony?

Permit fees range from $120 (overlay) to $150–$200 (like-for-like tear-off) to $250–$350 (material change to tile). Fees are calculated at approximately $0.08–$0.15 per sq ft of roof area. A 2,400 sq ft home typically costs $150–$250 for a standard tear-off and replace permit. Structural engineer fees (for tile upgrades) add $500–$1,500 separately.

How do I schedule inspections after my permit is approved?

The City of The Colony's online permit portal provides an inspection-scheduling link once the permit is approved. You can schedule inspections 24/7 through the portal, or call the inspection scheduling line (number provided in the approved permit letter). Typical wait times are 3-5 days in off-season (October-February) and 10-14 days during peak season (March-September). Pre-tear-off deck inspection is required, followed by final inspection after shingles are installed.
